sounds like a rear wheel speed sensor to me.

that is the rear wheel speed sensor (RWSS) under that cage. the ebrake
switch is at the pedal in the cab. and that isn't a proportioning
valve, it's a distribution block. all just FYI.

actually, yeah it did. it's a tight fit with the O ring in there once
it's rusted for a while. with enough wiggling persuasion you can get
it out. I think I broke mine both loose by tapping a straight slot
screwdriver between the plastic and the diff housing (probably a bad
idea, but it worked)

doesn't screw, just slip fits with an O ring.
have a look at a Dakota's RWSS versus an F250's:

They both slip-fit into the same bore. Just a good reference so you
know what it is that you're looking at pulling out.
